 NAME
      authck - check internal consistency of Authentication database

 SYNOPSIS
      authck [-p] [-t] [-a] [-v] [-d [ domainname ]]

 DESCRIPTION
      authck checks both the overall structure and internal field
      consistency of all components of the Authentication database.  It
      reports all problems it finds.  Only users who have the superuser
      capability can run this command.	When pwck is used with the -s
      option, authck is run with the -p option automatically.

    Options
      authck recognizes the following options and tests:

	   -p	   Check the Protected Password database.  The Protected
		   Password database and /etc/passwd are checked for
		   completeness such that neither contains entries not in
		   the other.  The cross references between the Protected
		   Password database and /etc/passwd are checked to make
		   sure that they agree.  However, if Nis+ is configured in
		   your system, the password table is also checked before
		   reporting a discrepancy.  This means that a discrepancy
		   would not be reported for a user that does NOT exist in
		   /etc/passwd but exists in the Protected Password database
		   as well as the Nis+ passwd table.  Fields in the
		   Protected Password database are then checked for
		   reasonable values.  For example, all time stamps of past
		   events are checked to make sure that they have times less
		   than the times returned by time(2).

	   -t	   Fields in the Terminal Control database are checked for
		   reasonable values.  All time stamps of past events are
		   checked to make sure they have times less than those
		   returned by time(2).

	   -a	   Shorthand equivalent of using the -p and -t options
		   together in a single command.

	   -v	   Provide running diagnostics as the program proceeds.
		   Produce warnings when unusual conditions are encountered
		   that might not cause program errors in login, password
		   and su programs.

	   -d	   Removes Protected Password database entries that are not
		   found in the Nis+ passwd table.  Nis+ users may have an
		   entry in the Protected database and not in /etc/passwd.
		   Thus, this option removes orphaned Protected database
		   entries: orphaned entries can exist for deleted Nis+
		   users.  The optional domainname specifies the desired

		   is not specified, the local domain name is used.
